No. 618,937.. In Great Britain Jilly 9, 1931 5 Claims.

' This invention relates 'to detergent composi= tions and particularly to compositions containing a compound which comprises a long 'alkyl chain and one or more sulfonic groups and a d substance adapted to increase the detergent properties of such compound. An object of detergent compositions containing compounds of Other objects will appear hereinafter.

These objects may be accomplished according 15 to my invention which comprises admixing a 20 vide a detergent composition which is adapted to which cleansing bath or solution is particularly adapted for cleansing textile materials and particularly wool and woolen materia My invention is based upon my discovery that,

method of manufacturing the cleansing solution,

4 as the glue and the detergent substance may be added separately or together to the water, without previous admixture, with the production of satisfactory cleansing solutions or baths.

As suitable long chain detergent substances 45 which may be employed in accordance with my invention, I may mention: the sodium salt of cetyl benzyl ether sulfonic acid, the sodium salt of cetyl sulfoacetate, the sodium salt of octadecenyl (oleyl) sulfoacetate, the sodium salt of beta-sulfoethyl oleate.

In order to more clearly illustrate my invention and the preferred mode in which I contemplate carrying the same into effect, the following examples are given:

Example 1.--A dry composition is made by incorporating together, e. g., by milling, 1 part of the sodium salt of cetyl sulfobenzyl ether and 9 parts of glue.

10 parts of this mixture are dissolved in 1000 parts of water to give a solution possessing a much more potent scouring action than is shown by the solution of 1 part of the sodium salt of cetyl sulfobenzyl ether in 1000 parts of water.

Example 2.- parts of glue are added to a wool scouring bath consisting'oi 2 parts of the sodium salt of cetyl sulfoacetate in 1000 parts of water. The scouring bath shows, a surprising increase in securing efliciency. 10

While the strict chemical nomenclature'has been employed, it will be understood that the compounds referred to may be made from commercially available alcohols, i. e., the respective derivatives may be made irom the commercially available cetyl, oleyl, and the like alcohols, or from alcohols obtainable from sperm oil or by the reduction of fatty acids and acid mixtures obtained from other sources and such compounds may be employed in the crude state as well as m in the purified state.

While I have disclosed compositions or cleaning baths composed of certain specific compounds, in specific propo ons, it will be readily 2s understood by those skilled in the art that the compounds and proportions employed may be widely varied without departing from the spirit of my invention. Accordingly, the scope of my invention is to be limited solely by the appended claims construed as broadly as is permissible-in 39 view of the prior art.

I claim:

1. A detergent composition suitable for addition to cleansing baths for textile fibers comprising substantially the sodium salt of beta-sulfoethyl oleate, and glue.

2. A detergent composition suitable for addition to cleansing baths for textile fibers comprising substantially the sodium salt or cetyl sulfo- 40 benzyl ether, and glue.

3. A dry composition suitable for addition to cleansing baths for textile fibers comprising substantially about one part of the sodium salt of cetyl sulfobenzyl ether, and about nine parts of 4 glue.

4. A detergent composition for textile fibers comprising a compound selected from the group consisting of the alkali-metal salts of cetyl-suitobenzyl ether, cetyl-sulfo-acetate, octadec'enyl- 'sulfoacetate and beta-sulloethyl-oleate, and a protective colloid selected from the group consisting of glue, gelatine' and islnglass.

5. A cleansing bathfor textile fiber comprising an aqueous solution of a. composition as defined in claim 4.
